Variant summary

Our verdict is Benign. The variant received -11 ACMG points: 0P and 11B. BP4_ModerateBP6BS1BS2

The ENST00000375401.8(KDM5C):c.536G>A(p.Arg179His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000335 in 1,209,054 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 121 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R179C) has been classified as Benign.

Genes affected

KDM5C (HGNC:11114): (lysine demethylase 5C) This gene is a member of the SMCY homolog family and encodes a protein with one ARID domain, one JmjC domain, one JmjN domain and two PHD-type zinc fingers. The DNA-binding motifs suggest this protein is involved in the regulation of transcription and chromatin remodeling. Mutations in this gene have been associated with X-linked cognitive disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2009]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.11263651).

BP6

Variant X-53217264-C-T is Benign according to our data. Variant chrX-53217264-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 211252.

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000351 (385/1097668) while in subpopulation NFE AF = 0.000437 (368/841841). AF 95% confidence interval is 0.0004. There are 0 homozygotes in GnomAdExome4. There are 117 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High Hemizygotes in GnomAd4 at 4 XL gene
